Create a highly detailed 3D model of a Tokyo Ghoul-inspired character. The character should have a dark, gothic aesthetic with a modern Tokyo streetwear twist. They should wear a tattered black leather jacket with red glowing veins running through it, a ghoul mask covering the lower half of the face (similar to Kaneki’s), and white hair with sharp, asymmetrical strands. The eyes should be red and black, glowing with a sinister aura. Add kagune tentacles emerging from the back, semi-transparent and glowing red with sharp edges. The background should be a rainy Tokyo alley with neon signs reflecting off wet pavement. Pose the character in a crouching, battle-ready stance with dramatic lighting from above.
